All Ireland league preview

Garryowen may start David Wallace against Carlow, who are unchanged, at Oak Park.

Gavin McCarthy returns from a long lay-off to number eight for Blackrock College. Michael Carrolll will stay at second row for the injured John Fitzgerald.

UL-Bohs are not sure about the fitness of centre Coleman Finn. Rob Desmond comes in on the wing. Second row Brian Dineen may have to switch to number eight to fill in for regular Anthony Hartigan.

Buccaneers will be without Ted Robinson and Chris Keane at home to Terenure College.

Leaders Clontarf hope centre Conor Mahony will be inspired against his old teammates of Cork Con at Castle Avenue.

UCD will have the contracted trio Shane Moore, Des Dillon and Brian O'Riordan in Ballymena.

Ballymena are riding high in second place in the table, having already dispatched Carlow and Clontarf at home. They have conceded the least tries (10) and the least points (83) in the division.

Lansdowne are unchanged at home to Shannon.

St Mary's College will have openside Shane Jennings and wing John McWeeney back against Galwegians.
